You're just asking for trouble, IMHO. First, those switches are for your brake lights, too. Anything you do to them will either disable the brake lights or they will be on all the time...same difference. Besides, if it died while moving it would have nothing to do with the brake switches.

Had a brake switch problem with my '05 Burgman 650. After a couple years it would hesitate, or run lumpy and eventually wouldn't run. After I got home on a flat deck truck. I pulled apart the contacts on the front and rear brakes levers. Scraped and cleaned the contacts. Solved the problem and I now do them each spring. No further problem.

So I have to assume that unlike the 400 this model has separate switches for the brake light and interlock? Otherwise it should run lumpy every time you use the brakes.

I've about got the hang of it, lol.
My actual starting procedure is thus: press start button; turn on ignition; pull left brake (or clutch); release start button. This avoids the arc on the start switch contacts when they break due to the high headlight current across the contacts (can cause dead headlights). Mostly a problem with two-headlight bikes.

I didn't reread everything in between, but back in post 3 you jumpered the connectors but got CHEK and still no start. So that must not be the problem?
